Abstract

Spinal implants (100), spinal rod approximators (10) for seating a stabilizing rod (R) in a rod-receiving portion (108) of a spinal implant (100), and methods for using the same are provided. In one embodiment, a spinal rod approximator (10) is provided including an elongate member (12) having a grasping member (14) formed on a distal end thereof, and a rod pusher member (16) slidably mated to a mounted on the elongate member (12). The grasping member (14) is effective to grasp a portion of a spinal implant (100), and the pusher member (16) is effective to grasp and engage a stabilizing rod (R) and push the rod (R) into a rod-receiving portion (108) of the spinal implant (100) being grasped by the grasping member (14).
